Due to problem with Nagios probe (https://tomtools.cern.ch/jira/browse/SAM-650) no CE tests have been received for sites ‘Australia-ATLAS’ and ‘UKI-NORTHGRID-LANCS-HEP’ in June and July. Therefore monthly availability and reliability numbers for these sites are broken and they are very low. Note that the fix for https://tomtools.cern.ch/jira/browse/SAM-650 has been released to Production on the 3rd of August. The sites numbers are not considered for computing the numbers for the federation in the WLCG report of July 2010
